FIRE    BRICK    DEPARTMENT 

GOOD  material  is  the  factor  of  supreme 
importance  in  all  manufacturing  busi- 
ness. During  the  growth  and  expansion  of  the 
fire  brick  business  from  small  beginnings  to 
the  present  output  —  corresponding  to  the 
growth  and  demands  of  the  iron  and  steel  in- 
dustries— it  has  been  the  aim  of  this  company 
to  maintain  the  lead  in  supplying  all  demands 
for  high  grade  fire  brick  and  refractory  mate- 
rial. To  this  end,  all  clay  deposits,  seemingly 
worthy  of  investigation,  have  been  core  drilled, 
the  best  experts  employed  and  record  maps 
placed  on  file,  enabling  the  Company  to  open 
mines  in  the  irregular  formations  of  fire  clay 
with  exact  knowledge  of  what  will  be  opened. 
This  work  has  been  going  on  systematically 
for  over  thirty  years.  The  results,  with  the 
association  of  a  few  of  the  most  experienced 
and  successful  brick  manufacturers,  enable  us 
to  offer  the  following  unrivaled  list  of  well 
known  brands  of  fire  brick.  Some  of  the 
brands  are  specially  fitted  for  special  work,  as 
the  "  Benezet  "  for  blast  furnace  linings.  Some 
are  similar  in  character  to  others,  but  owing  to 
location  of  works  one  brand  may  obtain  a  more 
f a vorable  freight  rate  in  a  given  case.  Corre- 
spondence or  an  interview  will  determine,  ac- 
cording to  circumstances,  which  is  the  most 
suitable  brand  to  use.  With  a  wide  range  of 
records  on  hand,  the  broadest  experience  in

HARBISON-WALKER  REFRACTORIES  Co.,  PITTSBURGH,  PA. 


the  business,  and  the  good  will  of  over  seven 
thousand  patrons  to  maintain,  it  is  reasonable 
for  customers  to  assume  that  they  will  get  re- 
liable advice  and  careful  attention  to  orders, 
however  large  or  small. 

The  brands  included  carry  the  world's 
record  for  output  of  metal  per  furnace  lining, 
blast  furnace  stove  brick  that  neither  disinte- 
grate nor  become  vitrified  with  the  severe 
changes  of  temperature  and  blast  that  occur  in 
furnace  stoves  incident  to  conditions  connected 
therewith,  the  best  of  brick  for  cupolas,  rotary 
cement  kilns,  lime  kilns,  open  hearth  steel 
furnaces,  copper  smelting,  boiler  settings,  con- 
tinuous glass  furnaces  and  general  purposes 
where  high  temperatures  are  in  use. 

The  brick  intended  for  different  parts  of  a 
blast  furnace  lining  are  branded  "  Hearth  and 
Bosh,"  "Inwall"  and  "Top"  to  prevent  the 
mason  from  making  mistakes.  The  records 
held  by  these  brands  are  the  result  of  careful 
observation  over  a  long  period,  and  selection 
from  the  best  Pennsylvania  clays.  Our  Gan- 
ister  rock  used  in  making  4<  Star  "  Silica  brick 
is  selected  from  decidedly  the  finest  deposits 
of  this  rock  to  be  found  anywhere.  "Star" 
Silica  holds  the  best  continuous  records  in 
open  hearth  steel,  Talbot  and  continuous  glass 
furnaces.

MAGNESIA    AND    CHROME 
DEPARTMENT 

IN  this  department  we  manufacture  one 
brand  of  chrome  brick  specially  adapted 
for  use  where  chemical  action  destroys  other 
brick,  and  two  brands  of  magnesia  brick  for 
use  in  basic  open  hearth  steel  furnaces  or 
other  places  where  basic  material  is  required. 


HARBISON-WALKER  REFRACTORIES  Co.,  PITTSBURGH,  PA. 

ORES    USED    IN     MAGNESIA    AND 
CHROMEBRICK 

MAGNESIA   OR   CALCINED    MAGNESITE 

OUR  supplies  of  calcined  magnesite  are 
drawn  from  the  best  quarries  known. 
These  quarries  have  supplied  the  bulk  of  the 
calcined  magnesite  used  in  the  steel  trade,  and 
the  product  is  decidedly  more  uniform  and 
satisfactory  than  that  from  any  other  source  of 
supply. 

For  forming  bottoms  in  open  hearth  steel 
furnaces  we  furnish  a  special  calcined  magne- 
site running  low  in  silica. 

CHROME   ORE 

Oxide  of  chromium,  or,  commercially, 
chrome  ore,  is  the  least  responsive  to  chemical 
action  of  all  refractory  material  obtainable  at 
a  price  permitting  of  use  in  the  arts.  For  this 
reason  it  is  invaluable  where  chemical  action 
prevents  the  use  of  ordinary  material.  The 
ore  is  used  by  many  for  special  purposes. 
After  experimenting  with  practically  all  of  the 
known  deposits  of  chrome  ore  in  this  country 
and  abroad,  we  have  adopted  exclusively  for 
our  use  and  for  the  wants  of  our  trade,  two 
qualities  which  we  consider  superior  to  any- 
thing on  the  market.  These  are  as  follows  : 

First — "Special"  low  silica  ore,  which  we 
recommend  for  practically  everything  in  con- 
nection with  basic  open  hearth  steel  practice. 

Second — Fifty  per  cent,  ore,  which  we  rec- 
ommend for  chemical  manufacturers  and 
other  special  work. 

Consumers  will  be  supplied  with  the  above 
ores,  either  ground  or  in  lump  form,  on  short 
notice. 


HARBISON- WALKER  REFRACTORIES  Co.,  PITTSBURGH,  PA. 


MAGNESIA     BRICK 

THE  material  used  in  magnesia  brick  is 
watched  carefully,  the  analysis  being 
kept  at  a  point  that  insures  the  highest  stan- 
dard as  to  refractoriness,  and  the  ingredients 
are  combined  so  that  the  brick  excel  in  physi- 
cal properties. 

"Magnesia"  are  made  from  carefully  se- 
lected calcined  magnesite,  of  a  quality  that  has 
been  found  most  satisfactory  and  uniformly 
reliable  for  all  work  connected  with  steel  man- 
ufacturing.

CHROME     BRICK 

CHROME  BRICK  are  used  as  a  neutral 
V_^  course  to  separate  the  fire  clay  brick 
used  in  lower  courses  of  open  hearth  steel 
furnace  hearths  from  the  magnesite  brick  used 
for  the  inner  and  upper  courses.  Also  for 
paving  floors  of  gas  ports  as  far  from  hearth  as 
slag  is  liable  to  splash  onto  silica  brick,  and  for 
quick  repairs  while  furnace  is  at  working  heat, 
being  specially  suited  for  the  latter  purpose,  as 
they  are  not  affected  by  sudden  changes  of 
temperature.  A  few  courses  of  chrome  brick 
will  be  found  useful  in  lower  portions  of  soak- 
ing pits,  or  wherever  slag  or  cinder  is  apt  to 
cut  out  ordinary  fire  brick. 

In  copper  furnaces  chrome  brick  are  used 
with  marked  success  for  lining  the  bosh  of 
the  furnace  from  the  tuyere  line  down,  also 
for  lining  the  settlers.  In  both  cases  the 
scouring  and  chemical  action  that  occurs  with 
the  slag  and  matte  acting  on  clay  brick  does 
not  occur  with  chrome  brick. 

In  the  side  walls  of  matte  and  refining  re- 
verberatory  copper  furnaces,  chrome  brick  will 
last  from  four  to  six  times  as  long  as  clay  or 
silica  brick.

BLAST     FURNACE    LININGS 

DLAST  furnace  linings  have  been  furnished 
for  many  small  furnaces  running  on  high 
fuel  consumption  and  high  top  heats  where 
magnetite  and  foreign  haematite  ores  are  used, 
Cornwall  ores  and  zinc  residium  ores;  also 
furnaces  using  fuel  high  in  sulphur,  and  others 
using  by-product  coke,  all  with  good  results. 

We  have  been  making  blast  furnace  linings 
for  the  last  thirty-five  years,  and  have  made 
more  than  90  per  cent,  of  all  the  linings  used 
in  the  United  States.  Our  linings  have  been 
used  under  every  imaginable  condition,  under 
hundreds  of  different  managers,  in  all  types  of 
furnaces,  and  with  all  classes  of  ore  and  fuel. 
The  uniformly  good  results  prove  that  reliable 
brick  were  furnished.  The  results  from  a  blast 
furnace  lining  are  too  important  to  depend  on 
a  hit  or  a  miss  lining. 

The  importance  of  calling  workmen's  atten- 
tion constantly,  while  placing  the  lining,  to  the 
fact  that  the  brick  are  made  for  a  certain  part 
of  the  furnace,  has  led  to  our  branding  on  the 
brick,  plainly,  that  part  of  the  furnace  for 
which  the  brick  are  made,  viz.,  "  HEARTH  AND 
BOSH,"  "!NWALL,"  "Top." 

In  order  to  get  uniformly  satisfactory  results 
about  a  furnace,  it  is  of  great  importance  that 
the  brick  used  for  lining  downcomers  and  flues 
be  able  to  resist  the  cutting  action  of  strong 
blasts  charged  with  ore  dust  and  the  cutting

BLAST   FURNACE   LININGS-CONTINUED 

particles  of  coke  that  usually  come  from  a  blast 
furnace.  "  BKXK/KT  PIPK  "  and  "  WOODLAND 
PIPK"  brick  are  made  specially  for  this  pur- 
pose and  give  good  results. 

The  present  blast  furnace  practice — closed 
top  furnaces,  high-pressure  hot  blasts,  etc., 
makes  it  more  essential  than  ever  before 
that  the  lining  be  the  best  obtainable.  At  an 
early  period,  and  continuously  to  the  present 
time,  this  branch  of  our  business  has  received 
special  attention,  resulting  in  tonnage  of  metal 
per  lining  not  thought  of  as  possible  previous 
to  the  records  we  have  recently  obtained. 
The  cut  on  page  50  shows  the  method  of 
building  or  breaking  joints  with  p-inch  and 
1 3  YI.  -inch  brick  in  the  construction  of  furnace 
lining  wall. 

BOTTOM     BLOCKS 

HTHE  cuts  on  page  51  show  our  present 
method  of  constructing  bottoms  and  the 
method  of  breaking  joints.  The  blocks  arc- 
all  alike;  having  parallel  sides  and  being 
made  under  heavy  pressure,  they  are  close  in 
bond  and  true  to  shape.  This  enables  the 
mason  to  make  a  closer  bottom  with  less 
trouble  than  could  be  done  with  the  blocks 
formerly  made  on  radial  lines.

BLAST     FURNACE     STOVE     BRICK 

D  LAST  furnace  stove  brick  are  only  second 
*-*  in  importance  to  the  furnace  lining,  for 
the  reason  that  it  is  not  as  costly  to  cut  a  stove 
out  for  repairs  as  to  shut  down  a  furnace  for  a 
new  lining;  but,  owing  to  the  heavy  burden 
carried  and  the  disintegrating  tendency  of  hot 
gases  constantly  varying  in  temperature,  the 
difficulties  to  contend  with  in  making  a  good 
stove  brick  are  equal,  though  different,  to 
those  met  with  in  making  a  good  lining. 

The  essential  qualities  in  blast  furnace  stove 
brick  are,  capacity  to  absorb  heat  readily  from 
the  combustion  of  waste  furnace  gases,  readi- 
ness to  give  off  this  heat  rapidly  to  the  air  that 
is  blown  into  the  furnace,  and  strength  of  bond 
between  the  particles  of  fire  clay  to  resist  the 
disintegrating  action  of  the  hot  gases.  In 
addition  to  strength  of  bond  necessary  to  resist 
action  of  hot  gases,  it  is  essential  that  the  iron 
which  is  in  all  fire  clay  should  be  converted 
into  a  silicate  of  iron,  which  is  a  fixed  form  that 
is  not  acted  upon  by  furnace  gases.  Tin's  can 
only  be  done  by  making  the  brick  of  high  grade 
fire  clay  that  will  stand  a  temperature  of  2,500 
degrees  Fahrenheit  or  upwards  in  burning  the 
fire  brick  without  vitrifying  the  clay  in  same. 
In  service,  although  stove  brick  are  not  sub- 
jected to  the  intense  heat  applied  to  a  blast 
furnace  bosh,  the  weight  carried  and  long  con- 
tinued heat  are  apt  to  cause  a  gradual  fusing 
and  solidifying  of  the  brick,  unless  high  grade 
clay  with  a  liberal  margin  of  refractoriness  is

HARBISON-WALKER  REFRACTORIES  Co.,  PITTSBURGH,  PA. 


used  in  making  the  brick.  If  brick  are  made 
of  sufficiently  refractory  clay  but  not  well 
bonded,  or  made  by  any  modification  of  the 
dry  process,  and  not  burned  by  the  high 
temperature  above  referred  to,  in  order  to  con- 
vert the  iron  into  a  silicate,  they  are  apt  to  dis- 
integrate within  a  few  months  after  starting 
the  furnace.  At  the  temperatures  produced  by 
the  combustion  of  furnace  gases  in  stoves,  low 
grade  brick  are  apt  to  squeeze  and  let  down 
the  lining,  also  to  become  vitrified. 

Glazed  or  vitrified  substances  will  neither 
absorb  nor  give  off  heat  as  rapidly  as  porous  or 
rough  material. 

Through  lack  of  attention  to  the  above  re- 
quirements, we  have  been  called  upon  several 
times  to  replace  stove  linings  in  less  than  one 
year  from  date  of  construction.  Records  and 
non- vitrified  bats  from  old  stove  linings  show 
that  our  stove  lining  brick  are  perfectly  adapted 
to  the  service  required. 

In  connection  with  illustration  of  typical 
stoves  in  use,  a  cut  of  the  special  shape  used  in 
each  of  several  types  is  shown;  these,  and  all 
similar  shapes  for  stoves,  are  made  from  good 
clay,  burned  at  a  high  temperature  to  insure 
all  iron  in  the  clay  being  converted  into  the 
silicate  form  in  order  to  enable  the  brick  to 
resist  the  oxidizing  or  disintegrating  action  of 
the  hot  gases. 

For  cuts  of  stoves  in  general  use,  see  pages

COKE    OVEN     BRICK 

C(  >KE  oven  construction  has  changed  radi- 
cally in  recent  years.    Where  formerly  any 
cheap  clay  brick  were  deemed  good  enough  for 
the  purpose,  of  late  the  tendency  has  been  to 
use  the  highest  grade  brick. 

The  excellent  results  recently  obtained  from 
the  use  of  silica  brick  in  the  severe  service  of 
by-product  ovens,  and  from  the  old  beehive 
ovens  in  the  Connellsville  region  and  other 
places,  have  clearly  demonstrated  that  the 
silica  brick  is  the  most  economical  that  can 
be  used  in  this  work,  due  entirely  to  the  in- 
creased length  of  service  obtained  by  their  use. 

Our  kk  H-W  Crown  "  brick  are  made  for  the 
crowns  of  beehive  ovens,  and  in  addition  to 
their  extreme  refractory  qualities  are  especially 
adapted  to  hold  the  crown  rigid  and  true  to 
shape  through  varying  temperatures,  making 
in  all  a  more  thorough  construction  physically 
than  can  be  obtained  by  the  use  of  clay  brick. 

The  "XX  Sand"  brand  has  been  found 
specially  suitable  for  lasting  service  as  liner 
brick. 

-  The  fronts  and  floor  tile  are  made  of  fire 
clay.  Trunnel  heads  are  made  of  either  silica 
or  fire  clay,  as  may  be  desired.

After  20  years'  use  in  these  furnaces,  the 
"Woodland"  fire  brick  still  holds  its  enviable 
reputation  as  the  best  brick  in  the  country  for 
steel-melting  furnaces.  The  "Woodland  "  fire 
brick  secured  the  greater  part  of  this  trade 
when  it  was  first  introduced  into  the  market, 
and  has  held  it  on  its  merits  ever  since,  being 
used  in  more  than  seventy-five  per  cent,  of 
the  crucible  steel  furnaces  of  the  country.

page  71  will  be  found  a  system  of 
shapes  for  above  furnace  designed  by 
ourselves.  The  plan  differs  from  any  hereto- 
fore used  in  having  the  side  walls,  or  walls 
over  the  ports,  built  with  horizontal  joints, 
thus  doing  away  with  the  arched  side  walls. 

The  advantages  arc,  that  having  all  joints 
or  courses  of  brick  horizontal,  the  side  walls 
arc  not  inclined  to  pitch  into  the  furnace,  as 
with  the  old  style  of  shapes;  all  the  shapes 
extend  back  to  the  breast  wall,  thus  making  a 
tight  joint  the  full  height  of  the  furnace  and 
preventing  the  gas  from  working  up  between 
the  breast  wall  and  the  furnace  wall.  All  of 
the  walls  having  a  straight,  solid  bearing,  the 
settling  will  be  uniform  throughout  the  fur- 
nace, thus  avoiding  the  opening  or  shattering 
of  the  walls  by  unequal  settling.  The  shapes 
being  of  simple  pattern,  a  mason  can  build  a 
furnace  with  these  shapes  in  less  time  than  is 
required  with  others.

GENERAL  INFORMATION  ABOUT  FIRE  BRICK 

All  fire  brick  should  be  kept  in  a  dry  place.  Mois- 
ture, especially  in  cold  weather,  will  greatly  injure  any 
brick. 

Good  brick  work  depends  much  on  the  following 
points  : 

Use  of  good  fire  clay  (equal  in  refractoriness  to  the 
brick  itself)  applied  very  thin,  preferably  dipped 
and  rubbed  close. 

Slow  warming  up  to  expel  moisture. 

Attention  to  fact  that  fire  clay  brick  contract 
slightly  and  silica  brick  expand  trader  high  temper- 
atures. 

Lighter  burned  fire  clay  brick  in  roofs  will  usually 
give  better  service  than  hard  burned  brick. 

The  refractoriness  of  silica  brick  is  greatly  decreased 
by  sudden  heating  up. 

From  250  to  350  pounds  of  fire  clay  or  silica  cement 
is  enough  to  lay  up  one  thousand  brick.  Fine  ground 
fire  clay  should  be  used  for  laying  up  fire  clay  brick  and 
silica  cement  for  silica  brick.  In  first  class  brick  work, 
less  than  three  hundred  and  fifty  pounds  of  fire  clay 
per  thousand  brick  should  be  used. 

For  approximate  estimating  on  fire  brick  work,  use 
the  following  figures : 

1  square  foot  4^ -inch  wall  requires  7  brick 

1  square  foot  9-inch  wall  requires  14  brick 

1  square  foot  13^ -inch  wall  requires  21  brick 

1  cubic  foot  brick  work  requires  17  nine-inch  straight 

brick 

1  cubic  foot  fire  clay  brick  work  weighs  150  pounds 
1  cubic  foot  silica  brick  work  weighs  180  pounds 
1000  brick  (closely  stacked)  occupies  56  cubic  feet 
1000  brick  (loosely  stacked)  occupies  72  cubic  feet 

Magnesite  and  chrome  brick,  although  highly  refrac- 
tory, are  only  suitable  for  use  in  places  where  they  have 
to  withstand  the  action  of  hot  basic  slags,  fumes,  etc. 
Fire  clay  or  silica  brick  are  recommended  for  other 
places.
